Abstract
The invention relates to a method for eliminating smoke inside the boiler chimney, wherein said method comprises: mounting steam nozzle through to the steam generator on the inner wall of chimney; when there is smoke inside the chimney, starting the steam generator, via the steam nozzle to eject steam into chimney. The invention is simple and effective, with low cost.
Description
Technical field
The present invention relates to a kind of smoke and dust eliminating method of the method that flue dust in the boiler chimney is carried out smoke abatement and dust control, particularly boiler.
Background technology
At present, the boiler that China uses in vast town and country generally uses coal to act as a fuel, and often produces a large amount of flue dust that contains particulates such as dust, carbon black behind the coal burning and is discharged in the air through boiler chimney, and atmospheric environment is caused severe contamination.For this reason, people use methods such as mechanical bag-type dust, high-pressure electrostatic precipitation and spray for dust suppression that the flue dust in the boiler chimney is carried out dedusting, and wherein mechanical bag-type dust investment is big, the occupied ground area is big, system equipment is heavy, power consumption is high, and machinery and electric fault are many, and equipment is difficult to safeguard; High-pressure electrostatic precipitation then is present comparatively advanced perfect dust collection method, but also needs heavy accessory fan, and equipment investment is big, breaks down to be difficult to maintenance; Then there are defectives such as easy obstruction of nozzle and pipeline easily freeze in spray for dust suppression.Therefore, at present institute generally these three kinds of dust collection method results of use of use are all not satisfactory.
Summary of the invention
The object of the present invention is to provide a kind of smoke and dust eliminating method of boiler, not only simple, easy operating, and the device therefor fault is few, easy care, reduced investment, smoke medicining dust-removing effect are good.
The object of the present invention is achieved like this: a kind of smoke and dust eliminating method of boiler, on the inner wall of stack of boiler, install the steam jet that is connected with water vapour generation equipment, when having flue gas to pass through in the boiler chimney, open water vapour generation equipment, make it in boiler chimney, spray into water vapour and get final product by steam jet.
Because the spacing between the hydrone of water vapour is big, when in boiler chimney, spraying into water vapour, the hydrone of water vapour will wrap particulates such as the dust in the flue gas, carbon black round and round, and adhere on its surface, increase its humidity, its proportion is increased and automatic sedimentation, thereby reach smoke medicining dust-removing effect.Present stage, the discharge standard of boiler smoke was 120 milligrams every cubic metre, and the graceful blackness of Green is an one-level.And through environmental administration's monitoring, after adopting smoke and dust eliminating method of the present invention, particulate such as contained dust is less than 40 milligrams every cubic metre in the discharged flue gas in the boiler chimney, and the graceful blackness of Green is less than one-level, the flue gas that throat is emerged is white in color, and smoke medicining dust-removing effect is very obvious.Smoke and dust eliminating method of the present invention is not only simple, easy operating, and also used water vapour generation equipment fault is few, and easy care need not boiler structure is carried out big transformation, reduced investment, smoke medicining dust-removing effect is good.
The specific embodiment
A kind of smoke and dust eliminating method of boiler, on the inner wall of stack of boiler, install the steam jet that is connected with water vapour generation equipment, steam jet should uniformly be arranged on the internal perisporium of boiler chimney, steam jet can be perpendicular with the boiler chimney axis, also can be certain included angle with the boiler chimney axis, promptly the flow of flue gas direction in this angle and the boiler chimney is acute angle or obtuse angle.Water vapour generation equipment is ultrasonic wave steam generator, electrical heating steam generator or solar energy water steam generator, can also directly be communicated with the boiler furnace water jacket, and the water vapour that produces in the boiler furnace water jacket is fed in the chimney by steam jet.When having flue gas to pass through in the boiler chimney, open water vapour generation equipment, make it in boiler chimney, spray into water vapour and get final product by steam jet.The concentration of the water vapour that sprays in boiler chimney should can effectively increase the humidity on dust surface in the flue gas greatly like this, improves smoke medicining dust-removing effect.But the concentration of water vapour can not be too big, prevents the phenomenon that hinders flow of flue gas.The flow of the water vapour that sprays in boiler chimney is 0.3-10m
3/ s, thus the time that the hydrone in the water vapour contacts with dirt particle enlarged, help increasing the humidity on dust surface, improve the water vapour smoke medicining dust-removing effect.
Use dust collection method of the present invention can also in boiler furnace, spray into water vapour, also can play good smoke medicining dust-removing effect.
